and to supply a continuous and regulatedamount of the grain to the drill, while at the same time preventing the grain from banking up within the hopper or supply compartment.

A further object of the invention is to provide agrain feeder which will operate to feed the grain from opposite sides or points of the hopper to an intermediate outlet,

whereby the grain will be positively gathered and uniformly distributed and also uniformly and continuously conveyed to the outlet.

A still further object of the invention is to provide a grain feeder embodying a hop: per or compartment having an outlet and right and left hand feed screws or angers operating to carry the grain from opposite sides of the hopper toward the outlet, together witha guard or cover plate arranged to close the joint between the screws or augers and prevent choking of the grain therein and to guide and positively insure the feed of the grain to the outlet.

A still further object of the invention is to provide a feeder of the character described by which the feed of the grain to the feed screws by gravity will be insured, and

whereby any desired number of feeders of,

the type disclosed may be operated from a common shaft; v

The invention consists of the features of construction, combination and arrangement of parts herein fully described and claimed, reference being had to the accompanying drawings in which Figure 1 is a topplan view of a grain feeder constructed in accordance with my invention. Fig. 2 is a vertical longitudinal section on the line 22 of Fig. 1. Fig. 3 1s a vertical transverse'section on the line 3+3 of Fig. 1.. Fig. 4 is a top plan view with the cover plate removed. Figs. '5 and 6 are ing the shaft in motion.

' top and bottom perspective views of the cover plate;

In the illustrated embodiment of the lI1- vention, I provide a hopper or compartment 1 to contain the grain, which hopper or compartment is provided with a bottomwall 2 having a central partially circular trough or depression. 3, and sides 4 sloping downwardly and inwardly toward said depression. The end walls of the hopper are r0- vided with hearing openings 5 in Which is ournaled a shaft 6, held from longitudinal displacement by disks or-washers 7 and cotter pins or keys 8. Mounted on the shaft within the hopper are oppositely pitched or right and left hand feed screws or augers 9 and 1.0, which are partially seated in the troughor depression 3, and operate when the shaft is rotated in the proper direction to gather and feed the grain toward a central outlet 11 formed in one ofthe sloping sides 4: and intersecting the adjacent edge of the trough 3 at a point in line with the innerends of the angers. The shaft is preferably of angular form in cross section and the augers are provided with correspondingly formed bores, by which they 'aremounted upon the shaft for rotation therewith, while at the same time by removing the keys 8 and outer disks or washers 7 the shaft may be withdrawn endwise, thus freeing the augers' for removal. In practice, it will be understood that any desired number of hoppers or grain compartments may be employed, in connection with a corresponding number of sets of angers, and that all of these angers may be operated from one and thev same shaft 6, the series of interdependent feeders thus produced bemg ar-' screws will operate continuously even whenone wheel is checked by running into a depression in the ground, the other wheel keep- Associated with the'set of angers Q and 10 is a guard or cover plate 12, having a semi-circular portion 13 to fit over the upwardly projecting portions of the inner ends of the auger screws and close the joint between them, so as to prevent the grain from above entering between the adjacent ends of the screws and choking the working At one end the parts of the apparatus.

with an apertured flange plate is provide 14 which laps over upon the rear sloping side 4 and is connected therewith by a bolt 15, while the opposite end of the plate is formed to provide a segmental hood 16 and an apertured end flange 17 secured to the front sloping side 4 by a bolt 19. The hood tapers longitudinally and is of somewhat less width than the plate, which is correspondingly tapered, and at its outer end the plate is provided with a feed aperture 20 pression and thence for the passage of the grain from the inner ends of the angers into the hood and thence outward through the outlet 11. The-hood covers the outlet and prevents the outflow of any grain except that positively fed to the outlet by .the augers, as W111 be readily understood. 1

It will be evident from-the foregoing description that in the operation of the feeder the augers will convey the grain from all sides of the base of the hopper or compartnienfi, m which they are assisted by the flow. 0 t e the proyision of the depression ,3 in which the grain tends to collect and by which the gram is retained in engagement with the threads of the augers. 'The guard plate may be detached at any time by simply removing its connecting bolts, for convenience in cleaning; repairing and replacing the parts, the aft and angers being also readily removable as previously explained.

I claim 1. In a grain feede 2 a hopper having an outlet intermediate of its ends, a shaft ]OI1I- naled upon the hop er, right and left hand angers carried by t e shaft and operating to feed the grain inwardly to said outlet, and a guard secured to the hopper and having a partially circular portion covering the inner ends of the augers, said guard being provided with a hood covering the outlet with an entrance leading thereto in line with the inner ends of the angers.

2. In a grain feeder,.a hopper provided with an outlet, a shaft journaled in the ho per, right and left hand angers carried y the shaft and operating to feed the grain inwardly to said outlet, and a guard provided with a portion covering the inner ends of the augers, a hood covering the outlet,

3. In a grain feeder, a hopper having a bottom provided with a depressed portion, sloping sides leading thereto, an outlet 1n one ofsaid sloping sides centrally of the hopper and intersecting said depression, a shaft journaled upon the hopper in line with said depression, right and left hand angers carried by the shaft and operating to feed the grain inwardly to said central outlet, and a guard secured to the bottom of the hopper and having a partially circular portion covering the inner ends of the angers, said guard being provided wlth a hood covering the outlet and with an entrance leading thereto in line with the inner ends of the angers.

In testimony whereof I afiix my signature in presence of two witnesses.
